27 28 29 Q2 30 Suppose that a three-stage process had reliability ratings of .77, .7, and .96 at each station and that a failure at any station represented a failure for the entire process. If each station is given a redundant check with .87 31 reliability, what is the increase in system reliability? 32 33 Initial process with no redundancy 34 RI 35 R2 36 R3 + 37 Reliability 38 39 New process with redundancy 40 R1-r 41 R2-r 42 R3-r 43 Reliability-new 44 45 Difference 46 47
